Hello, i have tried a little bit around with psycopg2 and threads, I'am sharing one connection for all threads. When i'am starting the threads "normal" everything works without any Problem. When i'am starting the threads from another thread than i got a "segmentation fault" - i'am using locks. I'am sending 2048 Reqeuest at once. The "normal" Methode with one thread for every Request needs 10 seconds. The other Methode starting a thread and starting two other threads from this thread crashes after 10 to 40 requests with the segmentation fault error. Any Idea why? Its a 64 bit maschine. Maybe i'am making something wrong? Kind Regards -- http://mail.python.org/mailman/listinfo/python-list
